The compact design of the ISUDAR SU6901 allows for flexible placement. The most common and recommended location is under a car seat to save space and provide optimal bass distribution. Ensure there is adequate ventilation around the unit.
Petunjuk Pengkabelan
The subwoofer requires power, ground, and a remote turn-on signal, in addition to audio input.
Koneksi Daya

Figure 6.1: Power and ground wiring connections.
- Connect the red power wire (typically 480cm) to the positive (+) terminal of your car battery. Install the included fuse holder as close to the battery as possible.
- Connect the black ground wire to a clean, unpainted metal surface on the vehicle's chassis. Ensure a good electrical connection.
- Connect the blue remote turn-on wire to the remote output of your car's head unit. This wire tells the subwoofer to turn on and off with your stereo.
Koneksi Masukan Audio
The ISUDAR SU6901 supports both low-level (RCA) and high-level (speaker wire) inputs.
Input Tingkat Rendah (RCA)

Figure 6.2: RCA audio input connection.
If your head unit has RCA pre-outs, connect the supplied audio cable (500cm) from the head unit's RCA outputs to the "INPUT" RCA jacks on the subwoofer. This provides the best signal quality.
Input Tingkat Tinggi (Kabel Speaker)

Figure 6.3: High-level speaker wire input connection.
If your head unit does not have RCA outputs, use the high-level input. Connect the speaker wires from your head unit's speaker outputs to the high-level input terminal on the subwoofer. Refer to your head unit's manual for speaker wire polarity.
Sakelar Tingkat Masukan
On the control panel (refer to Figure 2.2), locate the "INPUT LEVEL" switch. Set it to "RCA" if using low-level inputs or "SPK" if using high-level inputs.
7. Operasi
Initial Setup and Adjustments
After installation, turn on your car's audio system. The subwoofer should power on automatically if the remote wire is connected correctly.

Figure 7.1: Subwoofer control panel for adjustments.
Gain Control (MIN/MAX)
- Adjust the "GAIN" knob to match the output level of your head unit. Start at minimum and slowly increase until the bass blends well with your main speakers without distortion.
Low Pass Filter (LOW PASS 50-150Hz)
- This filter controls the upper frequency limit of the subwoofer. Adjust it to blend smoothly with your main speakers. A common starting point is 80-100Hz.
Bass Boost (0-12dB)
- Use the "BASS BOOST" knob to increase the bass output at a specific frequency. Use sparingly to avoid distortion.
Kontrol Fase (0°/180°)
- The "PHASE" switch helps to align the subwoofer's output with your main speakers. Listen to music with strong bass and switch between 0° and 180° to find the setting that provides the most impactful and cohesive bass.
Kontrol Bass Jarak Jauh
- The included remote bass control allows you to adjust the subwoofer's output level conveniently from the driver's seat without accessing the main unit.
8. Pemeliharaan
- Jaga kebersihan subwoofer dan bebas dari debu serta kotoran. Gunakan kain lembut dan kering untuk membersihkannya.
- Pastikan semua sambungan tetap aman. Periksa kabel secara berkala untuk melihat tanda-tanda keausan atau kerusakan.
- Hindari memaparkan subwoofer pada suhu atau kelembapan ekstrem.
- Do not block the speaker grille or any ventilation openings.
